### Ball Millan overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.- ore and 25 steel. The ball mill

Lower capital cost. Vertimill® requires a simple and small foundation which means less floor space is required. In fact in the same application a Vertimill® has 50 less footprint than a ball mill. Lower operating cost. Vertimill® is an energy efficient grinding machine. They tend to grind more efficiently than for example ball mills

of the Bond ball mill grindability test. For all model based methods a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw. Morrell (1996) proposed a mathematical model for autogenous semi-autogenous and ball mills which is based on the motion of grinding charge inside the mill.
